He stays on a low daily dose of a steroid. He was on Prednisolone but there were some major nationwide supply issues with it so he was switched to dexamethasone. There are still some spotty supply issues with the pred so she just kept him on the dex. They do sometimes treat IBD with leukeran , it's normally done when it can't be controlled with something like prednisolone. I think they are probably the cases that fall in that grey area between IBD and small cell lymphoma. I have even read of cases where the cat was kept on a low dose of leukeran to keep the disease controlled. Leukeran actually does the same thing as a steroid but it is much stronger than the steroids that are normally used.
